Microsoft shows off multi-touch sensor prototype

Microsoft researchers on Thursday demonstrated a new, low-cost method for manipulating a digital desktop or wall display with two hands.

Called LaserTouch, the prototype is the latest invention of computer-vision specialist Andy Wilson, a researcher from the Microsoft Research's Redmond campus. Wilson has worked on Microsoft's Surface computing, among other projects. But more recently he's developed a sensing technology system that would allow people to retrofit any display--e.g., a desktop or projector--so that they could use their hands, instead of a mouse, to interact with the computer.
